  • Spread spectrum communication equipment
    Patent number: 5838721
    Abstract: A spread spectrum communication equipment comprises a correlator outputting a correlation output signal, a timing generator generating two timing signals in response to a correlation peak value, detecting circuits for detecting information of a correlation output signal based on either one of the timing signals, receiving information detected in either one of the detecting circuits and checking whether the information coincides with the ID code, a switching circuit for selecting connection or disconnection between the detecting circuits and a demodulator, and a control circuit responsive to outputs of the checking circuits for selecting connection or disconnection with the switching circuit.
    Type: Grant
    Filed: June 6, 1997
    Date of Patent: November 17, 1998
    Assignee: Uniden Corporation
    Inventors: Kising Chau, Yoshimi Takahashi
